Two datasets in the EOS-WEBSTER US County Data Collection provide county-level data for crop acreage, production and yield
statistics. Crop data for 22 different field crops were acquired from the National Agricultural Statistical Service (NASS)
for 1972 through 1998. One dataset provides data for individual varieties/types of each crop while the second dataset provides
summary data by crop only. Data can be subset by irrigated and non-irrigated areas. Sucrose content, where applicable, is
also included.
EOS-WEBSTER provides seven datasets which provide county-level data on agricultural management, crop production, livestock,
soil properties, geography and population. These datasets were assembled during the mid-1990's to provide driving variables
for an assessment of greenhouse gas production from US agriculture using the DNDC agro-ecosystem model [see, for example,
Li et al. (1992), J. Geophys. Res., 97:9759-9776; Li et al. (1996) Global Biogeochem. Cycles, 10:297-306]. The data (except
nitrogen fertilizer use) were all derived from publicly available, national databases. Each dataset has a separate DIF.
The US County data has been divided into seven datasets.
US County Data Datasets:
1) Agricultural Management
2) Crop Data (NASS Crop data)
3) Crop Summary (NASS Crop data)
4) Geography and Population
5) Land Use
6) Livestock Populations
7) Soil Properties
